我是'm trying to apply the new threshold/negativeColor features of Highcharts v3.0.2 to essentially the ' spline updating each second'的例子 .
在图表更新的动画期间，我在系列行中看到了奇怪的工件 - 它看起来像是动画到一组不同的控制点......然后它在动画（新数据）时快速恢复到正确的配置点进来）完成了 .
注释掉threshold / negativeColor功能会使这个视觉神器消失 .
我看到了一个bug吗？
更新：我发布以下代码作为示例，这是我添加的阈值/颜色/负色线（系列下的第一行）的股票高图演示（我的本地jquery是v1.10.2） . 这段代码看似行为不端 .

事实上它看起来像一个臭虫，据报道here . 此时您只能禁用动画 .
